Lens
Lens is a city that carries its past in plain sight. The twin slag heaps at Loos-en-Gohelle — the tallest in Europe at over 180 metres — rise from the flat Artois plain like slow-motion monuments, part of the Nord-Pas-de-Calais Mining Basin that UNESCO recognised in 2012. Coal defined this city for more than a century, and its absence still shapes the place.
What changed things was a museum. The Louvre-Lens opened in December 2012 on a 20-hectare former colliery, and has drawn over four million visitors since. It is now the second most visited museum outside Paris, and it gave Lens a new reason to be looked at — not instead of its history, but alongside it.
💛 What travellers fall for
People who come back tend to say the same thing: go to Stade Bollaert-Delelis on a match day. RC Lens averages over 37,000 per home game, and the atmosphere in that ground — opened in 1932, tight and loud — is unlike anything in a larger city. The Galerie du Temps repays a second visit too; the collection rotates.

How Lens came to be
Lens began as a fortification against Norman raids, and by 1180 it was under the Count of Flanders. Louis VIII granted it a city charter in the 13th century, the Flemish razed it in 1303, and it spent over a century under the Spanish Netherlands before the Treaty of the Pyrenees returned it to France on 7 November 1659.
Coal surveys in 1849 found seams beneath the surrounding plain, and the Lens Mining Company — founded in 1852 — remade the city entirely. The First World War destroyed most of it; the population of 18,000 halved under four years of occupation. A second wave of Allied bombing in the Second World War killed 500 and levelled 1,000 buildings. The last mine closed in 1986, leaving the terrils and the memory.

When to go
Hauts-de-France runs cool and damp for much of the year. Summers are mild rather than warm, and rain is possible in any season. Spring and early autumn offer the most comfortable conditions for walking the Louvre-Lens park or the slag heap trails.
